PSoC 5, 3 & 1 MCU

Anonymous

Hello, members.

I have a question about PSoC5LP Filter Component.

When I check the Custom coefficient, set the Filter class to FIR,

and set the same as the attached file (DFB Configuration FIR),

the value of Filter taps can not be changed from 2, and

when I check the Custom coefficient, set the Filter class to Biquad,

and set the same as the attached file (DFB Configuration Biquad),

the value of Order can not be changed from 2.

Why can not I change the value of Filter taps or Order from 2?

Also, how can I change the value of Filter taps or Order from 2?

Best Regards

Hello Shimizu-San,

The order / filter taps is updated depending on the number of custom coefficients and filter class.

If you enter adequate number of coefficients in coefficient entry text box, the order / filter taps will be updated once the user hit OK/ Apply. This has been demonstrated for FIR and Biquad filter class in attached figure.

Please note that in Biquad filter class, coefficients are taken in the order of A0, A1, A2, B1 and B2.

Best Regards,
